So you want to disenfranchise those who receive assistance from the public purse because you don't think it's right that everyone (where possible) should contribute to it, and you want to retain your utopian caring sharing New Testament anti-tithe free-hugs community only for those places where it would be "easy" to implement? Or do you not feel those under an oppressor's boot deserve freedom too?
Yeah, it's easier to just roll over and ignore those lesser off than the rest of us. Just like you're implying should be done in your taxless society. Even in the most generous scenario, there will always be people who don't think the same way you do.
And speaking of dictatorships, have you even seen what's happening in the United Kingdom and the United States lately?
